BARREL-HOOFI Ne MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,142, dated October 28, 1890.

Application filed February 8, 1890.

To all whom it may concern: Y

Be it known that I, FRANK GLANKLEE, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Improvement in Barrel-HoopingMachines, of which the following is a specification.

My invention is in the nature of an iinprovement upon the barrel-hooping machines designed for putting on the final hoop, for which a patent has been granted me, dated February 4, 1890. The gist of that invention consisted in a ring or annular platen to be interposed between the pulling-hooks and the barrel-hoop for the purpose of distributing the strain of the pulling-hooks on the hoop and thereby avoiding the boudin g or crimping of the hoop in putting it on.

My present invention consists in the peculiar construction of that ring or annular platen, whereby the hoop is not driven entirely on the barrel, but is allowed to project a little beyond the 'chine or ends of the staves, so that when the barrel is set away or stored for future use it may be subsequently tightened by driving the hoop all the way on, and ,the cra'cks which may appear from shrinkage are thereby closed to make a tight barrel.

Figure l is a side view of an old and wellknownV form of trussing-machine, with my invention applied, one side of the ring being shown in section. Fig. 2 is a face view of the ring, and Fig. 3 is an enlarged sectional view taken through the ring and the chine of the barrel.

A is a frame or table for holding the barrel.

B are arms extending up through the same and connected below with a cross-head C, which is raised and lowered by means of a screw-shaft and bevel-gear E. The upper ends of the arms B are hookshaped, and catch over the edges of my ring or platen P, which bears equally against the edge of the hoop. This ring P is formed with a groove G in its lower face, which is designed to receive the hoop H (see Fig. 3) when the application of power is made to drive on the hoop. On the inner side of the ring next to the chine of the barrel the ring has a stop flange or rim a, which is designed to strike the chine of the barrel and arrest the further movement of the ring before the hoop H is fully driven on. The bottom b of the groove is also inclined, the side Serial No. 339,743. (No model.)

.of the groove next to t lowest and the outer side of the groove being deepest. 'Ihe object of this inclination of he flange a being shalthe bearing-surface b for the hoop is to produce an outward strain on the upper edge of the hoop in driving it on, and thus prevent its top edge from curling inwardly, which it would have a tendency to d o on account of the taper of the hoop. After the hoop is driven on to the' extent shown-i c., with an eighth or a quarter of an inch of the hoop projecting-the barrel is stored away, and when it is required for use any opening which may have taken place from shrinkage is closed up by driving the hoop its full distance on thestaves by means of a flat ring, as shown in my previous patent, or by hand.

In making use of my invention the flange or rim a need not be continuous, but may be broken or cut away at intervals. The metal of the ring on the outside of the groove may also be cut away, if desired. I may also in some cases use a disk; or Irnay dispense with a continuous ring-shaped platen and construct a series of segmental platens, each having the inner edge arranged to strike the chine of the barrel before the hoop is fully driven on.

Having thus described my invention, what I claim asnew'is- 1. A platen for a hoop -driving machine having on its inner surface a flange or stopriin a, extending inside and below the bearing for the hoop, substantially as described.

2. A ring or platen for'a hoop-driving machine having an abutting ange or stop-rim a for the chine and a bearing-surface above it for the hoop, substantially as shown and described.

3. A ring or platen for a hoop-driving machine having abearing-surface b for the hoop arranged upon an incline, as described, to produce an outward strain on the upper edge of the hoop to counteract its tendency to curl inwardly, as set forth.

4. A ring or platen for a hoop-driving ma# chine having an inner abutting flange or stop-rim a for the chine and an inclined bearing b for the edge of the hoop, substantially as shown and described.
